i just bought my first jeep and looking under the hood found most of the wiring had been cut and the wires just wrapped back together. my question is . whats the best way
to get these wires connected solidly and as weatherproof as posible
solder and tape
slder and shrink tubing

Re: wiring

Best way is solder and heat shrink. And the best kind of heat shrink has an adhesive/sealant inside.

I've never found a local source for it, so I use 3M heat shrink and a product called Liquid Electrical Tape. It's a thick, black goo in a half-pint can from my local electrical supply house.

After soldering the joint I paint the connection with the LET, then immediately slide the heat shrink down and shrink it with a heat gun. I know it's done right when a little of the LET oozes out each end of the heat shrink.

I once tried to take apart a splice done that way, to no avail. Everything was stuck together so tight that I was slicing off little pieces of heat shrink and LET with a razor. I finally gave up and clipped the splice out.

Re: wiring

Jim Lou is correct.
There are three steps to an electrical connection.

1. Mechanical connection.
That would be the crimp connectors, or twisting the wires together.
Don't be fooled into thinking this is an electrical connection or you will be fixing things until the cows come home...

2. Electrical connection.
Silver bearing solder (Radio Shack p/n 64-013 is a fine example) is the way to go.
Never use acid core solder on electrical components.
The Radio Shack 2% silver solder is very good for electrical connections and sticks to damn near everything.

3. Insulation & Environmental protection.
I like to use a heat shrink tubing with 'Glue' in it.
(The 'Goo' Jim Lou was talking about)
The vinyl crap sold at Radio Shack is no good, you will have to hunt for good heat shrink tubing.

Jim Lou's idea about the Liquid Electrical Tape then heat shrink tubing makes sense to me.

There are crimp connectors with solder and heat shrink tubing already attached to them. Not real common, but worth the hunt.
Crimp, then when you use the heat gun to shrink the tubing, the solder melts into the joint.
Shrink and solder in one step. Saves fingers from the soldering iron too!
How they get the solder to go liquid at that low of a temp is beyond me.

When you get wire, use virgin copper wire.
Alloy wire (usually a dull color, not bright like copper should be) will corrode no matter what you do, be hard to solder, and is generally more trouble than it's worth.

Re: wiring

The best is to solder and shrink wrap. You can get by with the connectors and tape but soldering is always the best.
